ROTARY GR Application filed December To all 'whom 'it my concern:

`tains to make and Suse the same.

This invention relates to improvements in rotary grain scourers.

The object of the invention is to provide a grain scourer of this character having means whereby the grain passing therethrough will be thoroughly cleaned and means to convey the scourin'gs and other matter removed rom' the grain to a suitable place of deposit. l

With the foregoing and other objects in view, the invention consists of certainnovel featuresof construc- -tionl` combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figurev l is a vertical longitudinal sectional view of a grain scourer constructed in accordance with' the invention lFig. 2 is a vertical cross-sectional view of the same and Fig. 3 is a detail perspective view of one of the sections of the cleaning cylinder, v i

Referring more particularly to the drawings, l de; notes the supporting frame'of they machine in which jis revolubly mounted a cylinder shaft- 2 on which is arranged a cleaning cylinder-3.

are suitably bolted or otherwisesecured together. The cylinderis supported upon the shaft 2 by radiallyfdisposed arms or braces 5 arranged on the shaft'between the ends of the cylinder. The cylinder 3 is preferably closed at its forward end and in said closed end lis formed a centrally disposed feed opening 6 into .which is adapted to project a lower rightlangularly formed open ond 7 of a feed chute 8 which is arranged .in the forward end of the frame, as shown. The rear or oppo-y site end of the cylinder is preferably left open for the discharge of the cleaned grain therefrom, said grain inlfalling from the open end of the cylindenbeing refi;

ceived by a suitable receptacle not shown.

Each of the sections ofthe cylinder is preferably formed witha series of longitudinally disposedslots 9.arranged through the center of the same. Each'of the slots 9 is covered with a screen l() through which the L scourings and other` matter removed from the grain i adapted to pass. On the inner side of the sections 4 ofi' the cylinders are secured a series of radiallyprojecting Specification of Letters Patent.

The cylinder 3 is prcfer-l ably formed of a plurality of segmental sections 4 which AIN-SCOURER.

The blocks I2 of one row are prefer-l ably arranged opposite the spaces between the 'blocks ings.y The inner side of each of the sections 4 ofthe cylinder are preferably covered with an abrasive material 13, said material being preferably in the form of emery or line scouring sand and preferably applied to thesecfabric, suchas canvas or ducking which is afterwards coated with glue and sanded with4 emery or other suit able abrasive material. The outer sides of the blocks l2 that used on the inner side of the sections 4. The blocks l2 are provided to increase the scouring surface of the cylinder and to form stirring devices by means of which the grain is more readily distributed over the through.

Arranged in the frame l below the cylinder are inf lowerends with a centrally disposed troughl in which is revolubly mounted a spiral conveyer I6. The scourthrough the screened slots 9 in the cylinder andfalls on to the guide-boards 14 which conduct the same to the trough 15 from which` it is removed by the conveyer 16 to a suitable place of deposit.

On the forward end of the' shaft 2 is mounted a beveled gear Wheel 17 which is engaged by a similar gear I8 on a suitably supported drive shaft I9 whereby the cylinder is revolved. On the forward end of the shaft 2 adjacent to the inner side of the gear l7 ismounteda sprocket wheel 20 whichy is connected by a sprocket chain 2l with a sprocket pinion v22 on the forward end 'of the shaft onthe conveyer 16 whereby motion is imparted tojsaidconveyer from the cylinder shaft.

' From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of/thelinvention will bereadily understood 'Withoutjiequiring a moreA extended explanation.

p Various ,changes lin the form, proportion and the minor details of construction maybe resortedl to without departing from the principle or sacrificing any of theadvantages ofr theinvention,` as dened by the-apv pended claims. v

' thus described' my invention, what I. claim asf'new and desire to secure by Letters Patent, iste- In a rotary grain scourer, a supporting trame, o. shaft ljtmriiale-d for rotation therein, a 4scouring cylinder fixed Vupon and for. rotationjwith the shaft and comprising a tions by first gluing'to the inner side thereof a suitable are also covered with an abrasive material similar tov interior surface of the cylinder while passing thereclined guide-boards 14 whichare connected at their in longitudinal rows on each side of the row of slots 9 of the other row, as clearly shown in Fig. 3 of the draw'- i ings and other material removed from the grain passes v plurality of connected segmental sections, said cylinder being provided with screened discharge openings and having one of its ends Wholly open and its other end closed by a head having a central inlet opening, a series of triangular projections arranged at spaced intervals over the inner surface of the cylinder, and serving to spread the material within the lattelge fabric covering applied over the whole inner surface of the cylinder, and having a coating of abrasive material, a feed chute having an angularly disposed portion projected into said inlet opening and arranged concentric with the shaft. and menus for driving the latter.

In testimony whereof have hereunto set my hand in presence of two subscribing witnesses. SAMUEL T. WILSON.
